MEANS FOR SECURING RESILIENT TIRES TO VEHICLE-WHEELS.

SPECIFICATION forming part of Letters Patent No. 680,392, dated August13, 1901. Application filed March 15, 1901. Serial No. 51,366. (Nomodel.)

enable others skilled in the art to which it ap pertains to make and usethe same, refer ence beinghad to the accompanying drawings, and to theletters of reference marked thereon, forming part of this specification.

This invention relates to means for securing resilient tires tovehicle-wheels provided with metaltires thereon; and it consists,substantially, in making the inner portion of the resilient tiresomewhat wider than the metal v tire of the wheel and with its interiorsurface flat and with transverse grooves or openings therein, throughwhich bolts can be passed when the resilient tire is secured upon awheel. This I do by means of annular flanges provided on their innersurfaces with lugs which engage each side of the resilient tire. Theseflanges extend inwardly. sufficiently to overlap the metal tire and alsoa portion of the wheel-rim when they are in place thereon. These flangesare secured to the Wheel by means of bolts passing through the flangesand the grooves or openings in the resilient tire, which bolts whenscrewed up operate to press the lugs on the annular rims into each sideof the resilient tire and also to compress the inner portion of theresilient tire to the same width as the metal tire on the wheel-rim,against which, as well as against the wheelrim, said flanges firmlyseat, which operates to firmly secure and retain the resilient tir inplace on the wheel.

These and other features of my invention are hereinafter set forth anddescribed, and illustrated in the accompanying drawings, in which-Figure 1 shows sections of the resilient tire, the annular flanges, themetal tire, and the wooden rim when the resilient tire is in place. Fig.2 shows a cross section of the same, on the line a; a; in Fig. 1, beforethe annular flanges are compressed against the metal tire and the woodenwheel-rim. Fig. 3 shows a cross-section of the same, on the line y y inFig. 1, after i tire, showing the grooves or openings in its interiorsurface. section of a modified form of my invention.

In the drawings thus illustrating my invention, A is the woodenwheel-rim, and B the metal tire thereon, both of which are preferably ofthe usual construction.

0 is a resilient tire, made of rubber or other resilientsubstance, withthe innerportions 0 thereof wider than the metal tire B, as shown inFig. 2, and with its interior surface 0 flat, so as to contact with theflat periphery of the metal tire B. Transverse grooves or openings c arealso made in the inner portion 0' of the tire, preferably openingthrough the interior surface thereof, as clearly shown in Fig. at. Theannular flanges D are made in continuous rings, the peripheries D ofwhich curve outward, asillustrated in Figs. 2 and 3. On the portion ofthe inner faces of the flanges D extending beyond the metal tire D thereare two or more rows of inwardly-projecting lugs cl. These lugs 01 arepreferably made of considerably-greater width annularly than radiallyand have their outer ends rounded, so that when they are forced into thesides of a resilient tire 0 they will not cut or tear the resilienttire, but will simply press back the resilient substance until theyembed themselves therein. These lugs cl may be made ofsuch annular widthand at such distances apart as may be desired. In the drawings I haveshown two rows of lugs 01 on the annular flanges D, the flanges d in onerow being intermediate to those in the other row. I can, however, usemore than two rows of lugs d and locate them on the flanges D, as may bedesired. At intervals corresponding with the slots or openings 0 in theresilient tire C, I make bolt-holes cl in the flanges D, in which boltsE, preferably provided with beads e and nuts 8, are inserted, which whenscrewed up press the lugs 61 on the flanges D into the sides of theinner portion 0 of the resilient tire O and also compress that portionof the tire O to the same width as the metal tire B, thus seating theflanges D D firmly against the edges of the metal tire B and sides ofthe Fig. 5 shows a transverse wheel-rim A and firmly securing theresilient tire O in place on the wheel. In the drawings anddesoriptionthereof I have located the bolts E immediately adjacent to the peripheryof the metal tire B. They can, however, be located somewhat above theperiphery of the metal tire or can be inserted through holes made in therim of the wheel inside of the metal tire. I, however, prefer theconstruction hereinbefore described, as I believe I secure the bestresults therewith.

In Fig. 5 I show a modified construction of my invention, in which themetal tire B is made with a flange D thereon, and the other flange D ismade removable, as hereinbefore described. Both of these flanges havethe inwardly-projecting lugs d on their inner faces, as hereinbeforedescribed. The resilient tire 0 being made wider than the annular faceof the metal tire B, as hereinbefore described, can in like manner becompressed between the permanent flange D on the metal tire B and theremovable flange D on the opposite side of the tire with the sameresults as hereinbefore described.

Therefore, having described my invention ner surface wider than themetal tire, annular flanges adapted to be brought into contact with theresilent tire and compress it until the fianges contact with the sidesof the wheel-rim and the metal tire, two or more rows of obtuseinwardly-projecting lugs on the portions of the flanges contacting withthe sides of the resilient tire,and bolts passing through said flanges,substantially as and for the purpose set forth.

2. The combination with a wheel having a metal tire, of a resilient tirehaving its inner portion wider than the peripheral face of the metaltire, annular flanges adapted to fit against the sides of the resilienttire and compress it to the same width as the peripheral face of themetal tire, two or more rows of inwardly-projecting lugs extendingentirely around the inner faces of said annular flanges having the outerends thereof rounded and adapted to be pressed into the sides of theresilient tire, and bolts passing through said annular flanges adjacentto the periphery of the metal tire, substantially as and for the purposeset forth.

In testimony whereof I affix my signature in presence of two witnesses.
